    Surprised you used an iron core? Just curious since an air core wouldn't cost that much more in the end?

    They're all air cores, just made acetal inserts for the 2.5mH inductors.
    Thinking about machining cylindrical resistor heat radiators for them too.

    Would it be ok to lower the small tweeter inductor to the opposite end of the board running same direction?

    I don't think you would experience any issues putting the tweeter inductor down lower.

    I understand now, I like it, good stuff

    This would be easier to wire everything up and have the Neutrik right next to the TeCu posts....

    I would space the flat could farther apart... 6 inches if you can

    Like so? I can still get the Neutrik where I need it.

    Yes that's what I would go with

    All that electron delivered pigment would surely ruin their harmonics :p

    Still thinking on what fastener to use on the rear of the board to attach the driver cables before I break out the Cardas-Quad....Hmmm

    Does the factory IC actually make the connection between the Blades on the CRS+ crossovers?

    I always connect the blade to ground

    I meant was the IC connecting L to R blades in a closed circuit.

    Are you referring to a blade/Blade socket cable?

    No, I'm asking about the factory pin/blade IC cable itself. If the blades are actually used (closed) and transfer signal like the pins do.

    They do and they don't.

    The way the speakers work the signal is connected thru the negative speaker terminals, hence the requirements for a common ground amplifier

    Connecting the blade to ground is redundant but I still prefer to use it

    The blade on pin/blade only comes into play on non-common ground amps to connect a ground through the negative binding post path.

    That would be the same as strapping the grounds on a non-common ground amp, No?

    I'm asking these questions because I have an aftermarket 14 Ft Neutrik cable with both connectors live (+and-). I will cut in half and make 2ea 7 footers. Was not clear if I only need to use just one of the Neutrik's wire circuit connected to the pins of the X-overs, whether using the Dreadnaught or not.

    Thanks for you guys' input.

    Ordered the Super-Q 15mH inductors as I found a thread or two where others did the same. Besides, my SDA's are Power-Ported :)

    One done. Hopefully the SBD inductors show up before the weekend and I'll drop these in the XS-8TLs, and set them sideways...

    XS-8TL's, soon to be SDA-XS-8TL's.

    These MW's have every mod done to them, including focus rings. I have a set of 6502's with phase plugs and focus rings to go in the SDA slots....

    Interesting project. Which driver will be the SDA? Will this reduce output?

    6502's for the SDA's will increase midrange clarity over the 6511's (BTDT). The 6516's are also better sounding that 6510's in stereo slots (also tested this myself). These won't need any help in the bass dept; especially with the Super Q's and no PR to drive. The soundstage width is big like that of the CRS+ due to MW driver spacing, minus the often experienced tweeter strangeness because the tweeter is much closer to the stereo driver. I had these hooked up a couple of summers ago at the shop on old CRS+ crossovers (think I sent them to VSAT afterwards), brought them home, did more mods and wiring upgrades to the factory 8TL crossovers. Now it's time to see what they can do on the dreadnaught with all the upgrades.

    The CRS+'s need their PR's side-mounted. ;)

    Better yet, Power-Port your CRS's B)
